热处理质量的好坏直接关系到产品的机械性能.通常热处理炉的炉温为数百度至上千度,要求炉温在一定的控制精度范围内保温规定的时间,其中有些热处理工艺曲线还是多台阶的.目前国内对热处理炉的控制一般采用动圈式调节仪,这种仪器控制温度精度低、惯性大、反应不灵敏、易受干扰、成本高、工人劳动强度大、不能自动定时进入每一恒温段、无法实现群控.这种仪器容易失控,造成烧毁产品的事故,因此热处理 The quality of the heat treatment is directly related to the mechanical properties of the product.Generally, the temperature of the heat treatment furnace is several hundreds of degrees to thousands of degrees, the required temperature in a certain range of control precision heat insulation, of which some heat treatment process curve is still multi-step. At present, the domestic control of heat treatment furnace generally use dynamic regulator, this instrument control temperature accuracy, inertia, insensitive, susceptible to interference, high cost, labor intensity, can not automatically enter each constant temperature section , Group control can not be achieved.This instrument is easy to lose control, resulting in burned products accident, so heat treatment
